研究镧改性、钠基和钙基三种膨润土对河水中磷的去除效果.将1.6 g的镧改性、钠基、钙基膨润土分别投入到800 mL的清河河水中,清河水水质为劣Ⅴ类.试验结果表明镧改性膨润土的磷去除效果优于其他两种,对河水中总磷的平均去除率为77.41%,磷含量在第7天达到Ⅳ类水水质标准.同时镧改性膨润土对氮和含碳有机物也有一定的去除效果,在第7天对总氮的去除率达到最高值50.78%,在第3天对含碳有机物的去除率为18.34%.

1.6 g of La-modified bentonite,Na-bentonite,Ca-bentonite,respectively,were added into 800 mL of the Qinghe River water which is inferior V class water.The phosphorus removal effect study of three types of bentonite on the C,N,P in the water was made. The results showed that La-modified bentonite has better absorption of phosphorus than Na-bentonite and Ca-bentonite,the average removal rate was 77.41%,in the seventh day the phosphorus content of river water to meet water quality standards for Class Ⅳ.La-modified bentonite to remove nitrogen and carbonaceous organic material is also effective to a certain extent. In the seventh day of TN removal rate reached the highest value of 50.78%,in the third day of the removal rate of carbonaceous organic material of 18.34% for La-modified bentonite.
